Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, and particularly relates to a plate positioning mechanism for a hydraulic guillotine shearing machine. Background Art

[0002] Hydraulic guillotine shearing machines are often used to cut the blank of sheet materials with straight edges. The shearing process should ensure the linearity and parallelism requirements of the sheared surface of the sheet material.

[0003] The shearing operation steps are simple, the operation is frequent, the physical strength consumption is large, the speed is fast, and it is easy to operate by mistake. For large-sized sheet materials, in order to improve the shearing quality and minimize the distortion of the sheet materials, a plate positioning mechanism is generally used for positioning treatment. Moreover, in the shearing operation, it is not convenient to manually push large-sized sheet materials for loading and unloading. Therefore, in combination with the above problems, we provide a plate positioning mechanism for a hydraulic guillotine shearing machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a plate positioning mechanism for a hydraulic guillotine shearing machine, which solves the problems of plate positioning and loading and unloading during the working process of the shearing machine.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A plate positioning mechanism for a hydraulic guillotine shearing machine, including a front support table arranged at the front end of the feeding port of the shearing machine, and a lead screw slider transmission mechanism, a roller pressing plate feeding mechanism and a top cylinder which are distributed on the left and right sides of the front support table and arranged along the feeding direction of the plate. The roller pressing plate feeding mechanism and the top cylinder are both connected to the slider of the lead screw slider transmission mechanism and are driven by the slider to move synchronously;

[0006] The roller pressing plate feeding mechanism includes a mounting frame, a driving cylinder, an upper pressing roller, a lower supporting roller and a limiting roller mounted on the mounting frame. The upper pressing roller and the lower supporting roller are arranged up and down to clamp the end of the plate, and the upper pressing roller is driven by the driving cylinder to longitudinally lift and clamp the plate. The limiting roller and the top cylinder are both arranged at the front end of the plate, and one end of the top rod of the top cylinder is exactly corresponding to the end of the plate.

[0007] Preferably, the height of the front support table is consistent with the clamping height of the roller pressing plate feeding mechanism.

[0008] Preferably, the limiting rollers are arranged one above the other on the mounting frame, and the end of the plate abuts between the roller surfaces of the two limiting rollers.

[0009] Preferably, the telescopic rod end of the driving cylinder is connected to the roller frame of the upper pressing roller, and guide columns for guiding the movement of the upper pressing roller driven by the driving cylinder are arranged on the roller frame. One end of the guide column passing through the mounting frame is connected with a nut for limiting, and a spring is sleeved on the guide column. The spring is connected between the roller frame and the mounting frame.

[0010] Preferably, an adjustable mounting groove is transversely arranged on the slider, and the bottom screw of the mounting frame is connected in the adjustable mounting groove and locked by a nut. The distance between the roller pressing plate feeding mechanisms on the left and right sides of the front material supporting table is adjustable through the adjustable mounting groove.

[0011] The utility model has the following beneficial effects:

[0012] By arranging a front material supporting table, a lead screw slider transmission mechanism, a roller pressing plate feeding mechanism and a blanking cylinder, the plate is placed flat on the front material supporting table, and the material is supported by the front material supporting table to prevent the plate from being distorted and deformed during feeding due to its large size. The roller pressing plate feeding mechanism is used to clamp the end of the plate to position the plate horizontally. The lead screw slider transmission mechanism drives the roller pressing plate feeding mechanism to move and push the plate towards the feeding direction of the shearing machine for feeding. After each plate is cut, the remaining waste clamped on the roller pressing plate feeding mechanism is ejected by the blanking cylinder to realize blanking. BRIEF DESCRIPTION OF THE DRAWINGS
